Graphite bomb: a weapon that disables power grids by shorting high voltage lines.
The CBU-94/B graphite bomb releases 202 small BLU-114/B bombs that emit graphite filaments on high voltage wires, insulators and transformers, causing short circuits and power outages over a large area without explosions or fire. The weapon does not directly kill anyone. The blackout also disrupts radars, command centers and air defenses, so attacking aircraft can enter more easily.
